APPARATUS FOR ADMINISTERING HEATED AND MEDICATED AIR.

EEJPECIFIGATION forming part of Letters Patent No. 489,029, datedJanuary 3, 1893.

Application filed August 31,1892. Serial No. 444,619. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM S. MOLEAN,a citizen of the United States,residing at Saginaw, in the county of Saginaw and State of Michigan,have invented certain new and useful Improvements in Apparatus forAdministering Heated and Medicated Air; and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters and figures of reference marked thereon, which form a partof this specification.

My invention is an apparatus for administering and heating medicatedair.

It is a common thing to compress air and administer it to the airpassages of the body by tubes and mouthpieces for the purpose ofdilating the lungs and passages. It is also common to pass the air socompressed through medicinal fluids, the medicine being taken up by theair and thereby conveyed to the air passages.

My invention consists in heating the air so compressed and medicatingand conveying it to the body.

The figure, is a side sectional view of my apparatus.

A, is an air receiver, the air being pumped into it through the tube 1.It is provided with a pressure gage 4.

B, is the heater provided with a concave bottom B for receiving the lampL, and the 1 flue B passing through the air chamber for conveying theheat; and having the orifice and stop cock 7, on the side for drawingoff the heated air.

0, is a glass bottle partially filled with medicated fluid, D. At orjust above the bottom of the bottle there is an orifice into the bottleconnected by the tube 8 to the stop cock 7 of the heater whereby theheated air may be conveyed into the bottle G, and through the medicatedfluids. One or more bottles may be connected to the heater and as manydifferent fluids used as desired.

2 is a perforated tube projecting into the bottle 0 through which themedicated heated air is taken, as desired, through stop cook 10 and tube11. To end of tube 11 a suitable mouthpiece, or other pieces, may beattached as desired. The air is thus taken from the compressor A throughtube 5 into the heating receptacle B thence through tube 7 into theliquid D, bubbling up through liquid into chamber 0, through pipe 12,and tube 11 to the mouth, &c., being heated and medicated on its journeyto the mouth.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is In a device for heating, medicating andadministering compressed air, the combination with an air compressor andgage, of the heater B, provided with an air chamber for receivingcompressed air, and a chamber below the said air chamber for receivingthe lamp, or other heater, and provided with the vent B" passing throughthe air chamber, the pipe 5, with its valves, for conducting the airfrom the compressor to the top of the heater, the medicating chamber 0containing medicating fluid D,the pipe 8 with its valves, forconveyingthe heated air from the side of the heater B to the bottom or side ofthe medicating chamber and below and into the medicating fluid D, andthe perforated tube 12, valve 10 and tube 11 for conveying the heatedand medicated air to the lungs and air passages, substantially asdescribed, and as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
